Nyob rau hauv ib puag ncig niaj hnub no, cov teeb meem dej phwj los ntawm kev tsim kho kev lag luam tau pib kho kom zoo hauv tsev thiab txawv teb chaws. Hais txog qhov no, peb yuav tsum hais txog qhov xwm txheej ntawm decolorizing flocculants hauv kev kho dej. Yeej, cov dej phwj tuaj los ntawm ntau qhov kev lag luam yuav tsum tau siv decolorizing flocculants. Yixing Cleanwater yuav qhia koj txog kev paub txog thiab kev siv hauv ntau qhov chaw.
Ntau yam polymer decolorizing flocculants tau dav siv hauv kev lag luam dej thiab dej phwj tuaj txawv teb chaws, ntawm cov polyacrylamide (PAM) yog hom tseem ceeb ntawm decolorizing flocculant. Piv nrog rau cov tshuaj inorganic ntsev flocculants, PAM, raws li hom tshiab ntawm kev kho dej, muaj ntau yam zoo: yooj yim thiab siv tau yooj yim, cov nyhuv flocculation yog kaum ob npaug ntau dua li cov tshuaj inorganic ntsev decolorizing flocculants; ceev flocculation thiab sedimentation ceev, siab sludge dewatering efficiency; kev kho mob tshwj xeeb ntawm cov dej phwj tuaj; yooj yim cov cuab yeej yuav tsum tau, me me hneev taw; tus nqi kho mob tsawg; Cov dej phwj tuaj yeem siv tau thiab rov siv dua, thiab lwm yam.
Daim ntawv thov ntawmPAM decolorizing flocculant hauv ntau daim ntawv thov teb:
1. Daim ntawv thov hauv kev lag luam papermaking
Kev siv qhov hnyav molecular PAM ua ib qho decolorizing flocculant tuaj yeem ua rau cov nag lossis daus ntawm cov xim thiab lwm yam khoom siv hauv dej dawb thiab txo lawv qhov poob. Ntxiv 0.25 ~ 0.5% PAM rau cov ntaub so ntswg tuaj yeem ua kom cov av nplaum ntawm cov ntaub so ntswg los ntawm 40 ~ 80 npaug, txo cov khoom hauv cov dej dawb li ntawm 66%, nce cov hmoov tshauv ntawm cov ntawv, nce tus nqi khaws cov pigments xws li av nplaum dawb los ntawm 8 ~ 18%, thiab txuag 20kg ntawm pulp ib tuj ntawm ntawv. Ntxiv mus, tom qab siv PAM, turbidity ntawm cov dej dawb yuav txo tau zoo heev, txo cov pa phem ib puag ncig. Piv txwv li, cov khib nyiab tshem tawm ntawm cov kua dej dawb paug nrog pH = 6.8 yog 3000ppm. Tom qab tau kho nrog PAM nrog rau qib hydrolysis ntawm 5 ~ 10%, qhov hnyav molecular ntawm 5.5 ~ 10 lab, thiab 500ppm ntawm txhuas sulfate, cov dej dawb tuaj yeem hloov mus rau hauv cov kua tsis muaj xim thiab pob tshab, thiab cov khib nyiab tshem tawm raug txo kom qis dua 50ppm.
2. Kev siv decolorizing flocculants hauv kev kho dej
①Anti-scaling thiab descaling
Hauv kev lag luam dej thiab dej phwj kho, cov dej nyoos yuav tsum ua ntej kom meej. PAM decolorizing flocculants thiab inorganic coagulants feem ntau yog siv ua ke, uas tuaj yeem txo qis kev siv cov inorganic coagulants, zam cov khoom thaiv thiab corrosion vim yog siv ntau dhau ntawm inorganic coagulants, thiab tiv thaiv kev tsim cov nplai. 37.5 qhov chaw ntawm PAM nrog qhov hnyav molecular hauv qab 1 lab thiab 50 qhov chaw ntawm sodium tripolyphosphate yog siv los tsim cov nplai inhibitor, uas tuaj yeem tiv thaiv cov nplai ntawm cov khoom siv hluav taws xob loj heev.
②Kev kho cov dej phwj tuaj
3. Kev siv decolorizing flocculants hauv kev kho dej khib nyiab hauv kev lag luam qab zib
Cov kua txiv hmab txiv ntoo muab rho tawm los ntawm cov xovxwm los ntawm cov chaw tsim khoom qab zib feem ntau yog turbid thiab nws muaj pes tsawg leeg kuj yog qhov nyuaj heev. Txhawm rau kom tau txais cov kua txiv kab ntxwv huv, cov tshuaj clarifiers yuav tsum tau ntxiv. Yav dhau los, inorganic decolorizing flocculants feem ntau yog siv, tab sis nrog kev txhim kho ntawm kev lag luam qab zib, inorganic decolorizing flocculants tsis tuaj yeem ua tau raws li kev xav tau ntau lawm. Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm PAM hauv kev lag luam qab zib tuaj yeem nce sedimentation tus nqi los ntawm 20 npaug.
Hauv cov ntsiab lus, thaum peb xaiv polyacrylamide PAM decolorization flocculant raws li qhov xwm txheej tiag tiag, peb yuav tsum xaiv nws raws li qhov sib txawv daim ntawv thov scenarios thiab tej yam kev mob. Yog li ntawd, kev xaiv ntawm polyacrylamide kuj tseem ceeb heev.
Yog tias koj xav tau peb cov khoom, thov koj xav tiv tauj pebtiv tauj peb!
